           Summary: Dolphin freezes (and sometimes crashes) randomly after
                    some time
           Product: dolphin
           Version: 20.08.2
          Platform: Archlinux Packages
                OS: Linux
            Status: REPORTED
          Keywords: drkonqi
          Severity: crash
          Priority: NOR
         Component: general
          Assignee: dolphin-bugs-null at kde.org

  Target Milestone: ---

Application: dolphin (20.08.2)

Qt Version: 5.15.1
Frameworks Version: 5.75.0
Operating System: Linux 5.9.3-xanmod1-1 x86_64
Windowing system: X11
Distribution: "Arch Linux"

-- Information about the crash:
- What I was doing when the application crashed:
Doing anything on Dolphin (including nothing).
A freeze then appears after some time. If I wait about 30s or so, it usually
becomes responsive again.
If I try to use it when it is freezing, it might end up crashing.

The crash can be reproduced every time.

-- Backtrace:
Application: Dolphin (dolphin), signal: Segmentation fault
